An inside source told US Weekly that the royal couple plans on officially moving into their four-story, 20 room pad this summer, and adds that, "A baby is the main reason for the move."

(And if a baby is the reason for the movie, then they must be having a baby, right?)

Apparently they feel their cottage on the island of Anglesey isn't quite fit for their royal offspring because "They want to bring a child up in a secure environment."

(And I guess things don't get much more secure than Kensington Palace.)

In addition to being a wonderful place to raise a child, it sounds like Kate and William's new home will be pretty luxurious as well. It's currently undergoing a $1.5 million renovation, and the Duchess has plenty of decorating plans in the works.

Another insider says, "Kate is keen to put her stamp on the place with things she's bought on her travels. She felt certain pieces would be nice 'when we have a bigger home'."

Ok, so I guess the fact that they're packing up and moving to the palace doesn't necessarily mean a baby is imminent, but considering how comfortable they've been while living a fairly normal life on Anglesey, it does seem interesting that they're so ready and willing to give up their solitude a few months from now.

When my husband and I got married, we moved from an apartment to a nice three bedroom home in the suburbs because we knew that we wanted to be settled in a good neighborhood before the kiddos came along. Trading up to a bigger place is something plenty of couples do to prepare for a baby, so why would William and Kate be any different? (Oh, just forget the royal thing for one second.)

It certainly sounds like they're more than ready to start a family together, doesn't it? I mean, what are they going to do with 20 rooms if they don't start filling them up with kids?
